Reply to Joe 27 days in the past Exactly what is re-transmitted is infrared radiation. That is not affected by temperature. Infrared is a wavelength of sunshine that's invisible on the human eye.
In the ultimate visualization you may check out the identical cumulative CO2 emissions as you've seen earlier mentioned but now split
b. Re-emit the photon – This is certainly in the random course. So several of This is actually the calculated downwelling IR that warms the floor
I posted a little something on foodstuff security within the local climate coalition Web site very last year in the event you’re interested.
Reply to Albert Snapenstein one 12 months in the past I understand that as derived from very first principals the dry lapse charge during the troposphere is equal to -g/cp wherever g may be the acceleration of gravity and cp is the warmth capability on the environment at continual stress.
two many years in the past You said “Just before people started burning fossil fuels, The natural way happening greenhouse gases helped for making Earth’s local climate habitable. Without the need of them, the World’s regular temperature will be below freezing. So we recognize that even quite reduced, natural levels of carbon dioxide as well as other greenhouse gases will make a tremendous distinction in Earth’s local weather.
The described greenhouse outcome of CO2 just isn't in accordance with the molecular Homes of CO2. These ought to be handled quantum mechanically. The interaction with radiation and intermolecular interactions are described by quantum mechanics.
(Maintain your hand around a darkish rock with a warm sunny working day and you can come to feel this phenomenon for yourself.) These infrared waves journey up into your environment and can escape again into Area if unimpeded.
That’s amongst The explanations why a Greenhouse period of time has a more secure temperature round the planet.
The clever and accurate retort rather than my fewer mental bypassing The complete argument – see earlier article. Regards,.
Reply to Sarah Fecht one year ago Have you ever at any time nevertheless regarded another world to fossil fuels? In 1820 86% of your entire earth lived in Extraordinary poverty, of which only twelve% of the planet have been literate. Planes have designed us fewer xenophobic, & civilised in a extremely short time period. How would all of us get close to right now normally, absolutely devoid of assembly traces? ‘Horseback’, or steam-fueled modes powered by Wooden, ‘all’ matters driven by wood. Wooden we don’t really need to spare. Streets caked in manure. Meat & milk reliance. Regardless of whether resulting from mortality, the populace was just three billion nowadays, It might be a World of ruminants, undrinkable drinking water, and deforestation.
Reply to Lisa Goddard 3 years in the past Thanks, I’m once the physics describing the greenhouse result/system of heat transfer.

Your argument conflates infrared radiation with heat, but they aren't the exact same detail. The phenomenon of “warmth” is because of kinetic energy in the molecular degree, i.e., the motion of molecules and atoms. Infrared radiation is really a type of electromagnetic radiation and, although it could cause heat by creating molecules to vibrate (kinetic Vitality), It's not, itself, a form of warmth energy. In the specific case of warmth Strength, Of course, the 2nd legislation of thermodynamics states that “warmth” normally “flows” from areas of increased temperature to areas of reduced temperature.
